The production of high-quality films must be fully planned. Before the filming, we should make detailed planning of the interview idea, problem design and interviewee selection of the whole film. The more the pre-planning is in place, the more labor-saving and smoother the later shooting.

The determination of the interview idea. The interview idea has a decisive influence on the entire documentary. Before the interview, there must be a clear and detailed idea. For example, how we connect the entire film clip, how to arrange the interview sequence of different interviewees, and so on. Guided by the correct ideas, the entire interview process can be smoother and more efficient, thus ensuring the quality of the film.

Another important aspect is the design of the interview questions. The design of interview questions is an important part of the early planning of the documentary. The design of questions before the interview should follow the following principles: fit the theme, the questions should be designed to serve the theme, serve the character image; conform to the identity of the person, meet the knowledge and culture level of the interviewee, communicate with the interviewee equally, and stimulate the interviewee The desire to express; the depth of the documentary. The documentary is not simply a record of representation. The profound connotation behind the event or character is what the film really wants to express. Therefore, we must guide the interviewees to express their opinions more deeply through effective problem setting, more realistic expression of emotions, and ensure that the thoughts and emotions of the interviewees follow the idea of ​​film design.

One of the challenges that the interview may encounter is that the interviewee does not clearly understand the meaning of the question. I think the solution is to design the problem scientifically before the interview. The problem should be special, targeted, and ambiguous. There should not be too many modifications to the core issues to prevent respondents from being able to sort out the problems of the problem.
